Y Application icdJ'une 27.V

This invention relates to improvements in ampuls, vials or small bottles made oir-glass and particularly adapt-ed to contain liquid substances ot a volatile nature immun-e from contact with the air, thereby preventingv evaporatiomdissipation and deterioration of One of the'objects ot invention in the provision ot an 'ampul of thecharacter indicated, having a hernietically sealed closure, which may ybe readily removed when desired.

Another purpose 'is to provide a: territori cap applicable to the neck or the ampuhafter. 'the original stopper has been removed. said cap being close tting and having a lining adapted to preserve the contents from the vair. Y f

A further aim is to provide such devices in forms adapted for convenient use, relatively inexpensive in construction and effective' in their purpose. A

These several objects are attained by the novel construction, arrangement and combination oi". parts hereinafter described and,

shown in the accompanyingdrawing, torni ingV a material part of thisdisclosure, and

In this condition the contents are entered,v

'after which heat `'is 'applied to the small opening at the mouth until' the Vglass becornes melted. By using pliers the glass is ,.r'afivn outinto a fine thread', again heated and as itrvinelts the ainpul-is rotated in order to form .a spherical bead 15 of slightly greater diameterthanthe end of the neck,

forming a-*heiinetic seal.y

Vhen vit is desired touse a portion` of the contents, the bead 15 .is readily removed .f

by grasping it With a'pair of pliers or other implementholding the body firm,l and giv-y ing a'tivistwhich cause separation. i
